Solutions for material and energy efficiency
Fraunhofer Institute for Mechanics of Materials IWM
We can help you to define material and component properties that optimize their response to stresses and strains when in use and that make the greatest possible use of their potential.
More material could be saved when manufacturing wafers in future. Ultra-thin saws made of carbon nanotubes and diamond would be able to cut through silicon wafers with minimum kerf loss. A new method makes it possible to manufacture the saw wires. [more]
Internal coatings in the different sections of oil treatment plants are subjected to a variety of stresses. By conducting comparative tests, researchers are analyzing which materials are best suited to each individual section. [more]
Researchers have developed a method that can reduce engine friction and wear even during production of engine components. Special coatings can help to reduce fuel consumption and CO2 emissions. [more]
Solar cells must endure a lot: snow, hot summer days, rain and humidity. To provide maximum protection to the cells, the manufacturers embed them in plastic, usually in ethylene vinyl acetate (EVA). .
Everyone wants to have nice teeth. After all, a perfect set of teeth symbolizes health and youthfulness, and can even infl uence career prospects. If having pristine teeth calls for thorough oral hygiene, then how well or badly does a given toothpaste clean? How effective is it? What must it contain in order not to damage the structure of the teeth? Such questions are primarily of interest to manufacturers of dental hygiene products, and the answers are being delivered by researchers from the Fraunhofer Institute for Mechanics of Materials IWM in Halle. Through close collaboration with the Microtribology Centre μTC in Karlsruhe they have developed a new process for testing the abrasive effect of toothpastes, allowing this ‘abrasiveness’, as experts call it, to be compared and evaluated in the lab.

Cold cracking in high-strength steel presents major quality assurance challenges for the automotive and machine-building industries, since cracks are difficult to predict – until now. A new process can determine, as early as the design stage, if critical conditions for such damage can be prevented. This lowers development times and costs. [more]
